I'm trying to install Openstack on a single machine to do some testing.

I need it to have
- neutron
- Heat
- Cinder

I tried to install it using a proccess that seems very easy:

add the repository

apt-get install openstack

openstack-install

Everything is fine at the beginning
Anyhow, at a certain point I get this error

and the installaiton process goes on indefinitely
Have you ever faced something like this and do you know how to solve this?
